Suggestion: Housing "Plot Themes"

Why not att a slot to the exterior designs to redsign the housing plot lawn or whatever its called.

Like the ones we can change roof, exterior house theme, wall boundry etc.

What im suggesting is, let us choose from various themes for the plot area / lawn if you like.

For example:
Cobbles (+ additonal rock formations)
Snow (? Additional mounds of snow)
Tall grass
Gravel (mixed)
Sand (Beach like lawn / plot)
Water (with wooden planks to walk on to the house)
Ancient (with water cannals, plant wines, moss etc)
